6fe7377c22 revamp how we tokenck and store the InternToken 
In `InternToken`, we now coallesce everything into one
`Vec<MatchEntry>`, rather than using a vector and a map.  In the
token-check code, the various fields associated with a match are moved
into a struct.

61c2ce1522 use TerminalLiteral instead of TerminalString where appropriate 
This avoids a lot of unwraps and panics. I did copy the precedence code
but I plan to refactor that shortly.

9e529089d3 convert panics into Err results for byte-based regex 
We don't currently support byte-based regular expressions,
though it does seem like something that would be potentially
useful in the future.

25d89effd3 implement the rest of the lane table algorithm 
Or, at least, enough to pass the "torturous" `paper_example_g1_build`
test.

7515fccef6 inefficient version of the core lane table algorithm 
The missing piece is updating the lookaheads of the new states that wind
up getting created.
